template class mrpt::maps::COctoMapBase

A three-dimensional probabilistic occupancy grid, implemented as an octo-tree with the “octomap” C++ library.

This base class represents a 3D map where each voxel may contain an “occupancy” property, RGBD data, etc. depending on the derived class.

As with any other mrpt::maps::CMetricMap, you can obtain a 3D representation of the map calling getAs3DObject() or getAsOctoMapVoxels()

To use octomap’s iterators to go through the voxels, use COctoMap::getOctomap()

The octomap library was presented in [8]

Construction

COctoMapBase(double resolution)

Constructor, defines the resolution of the octomap (length of each voxel side)

Methods

virtual void getAsOctoMapVoxels(mrpt::opengl::COctoMapVoxels& gl_obj) const = 0

Builds a renderizable representation of the octomap as a mrpt::opengl::COctoMapVoxels object.
